Carda DEX swap feed

What the price

Tool for Cardano to get Dex SWAP operation, store it to the Database and broadcast it through the WebSocket.

DEXes

We have implemented 3 Dexes

• WingRiders
• MinSwap
• SundaeSwap

Dex can have more versions and more addresses per version.

Interface

• /health - Health check endpoint
• /assets - List of assets present in the database. This is a place, where pair asset_id with name and policy
• /exchange_rates - Calculate exchange rate. There is no information about decimal numbers
• /mean_history/TOKEN1_ID/TOKEN2_ID?count=<number> - Return mean swap price for tokens. Mean is not AVG, but ration on the pool address
• /asset_swap/TOKEN1_ID/TOKEN2_ID?count=<number> - Return last swap price for tokens.
• /socket/ - WebSocket endpoint for Live information about the swap.

Setting up

Run a Postgres instance and create an empty database for this project:

export DATABASE_URL='postgres://postgres:postgres@localhost:5432/wtp'
psql -U postgres -c 'CREATE DATABASE wtp;'
cargo migrate up
cargo run -- -s 'relays-new.cardano-mainnet.iohk.io:3001' -d $DATABASE_URL

Development

Add pre-commit hook:

ln -s ../../pre-commit.sh .git/hooks/pre-commit

How to modify the database schema

cargo install sea-orm-cli
sea-orm-cli migrate generate "your_migration_name"
# now edit the new migration file in ./migrations/src
cargo migrate up
sea-orm-cli generate entity -o src/entity

Run

# Ideal run parametres for WR
cargo run -- --socket localhost:3001 --database $DATABASE_URL --persistent  --start 57270168:17a26b5607a6f61fe89bf73a7a242ff4fa6dd6c667f3b2d6fc56bbcad644e90b
